I have a small domain that is strictly a Windows 2000 envirorment. I have 5 clients running 2000 Pro and the server running 2000 Server. On one of the clients, lets say computer "Fred" I can see computer "Barney" but when I try to access the resources on Barney it times out with the error message \\Barney is not accessible There are currently no logon servers available to service the logon request. I can still ping Barney by name or IP address after receiving the error message. All the other client machines can access Barney with no problems. Barney can see and access Fred's and the other client machines resources just fine. It seems like a SID problem to me, any ideas?...Thanks!
